Fox V3 Motif Helmets use our Magnetic Visor Release System (MVRS) to attach the visor. This Fox patented technology replaces screws with magnets - an entirely new approach to managing rotational forces. The visor is designed to stay firmly in place under roost, but release in a crash. In addition, the V3 helmet is equipped with the Multi-Directional Impact Protection System (MIPS). Mimicking the cerebrospinal fluid, MIPS adds a low-friction layer between the helmet and the head. This technology reduces the rotational violence otherwise transmitted to the brain. The V3 helmet features 4 shells and 4 EPS dimensions. This exhaustive range of helmet sizes provides the most accurate fitting helmet we have ever created. The interior features 14 intake and 4 exhaust vents to channel fresh air through the helmet and allow hot air to escape. A DriLex® Comfort Liner feels luxuriously soft against your skin and rapidly wicks sweat to keep you dry.
